Nihon Musanto

The Nihon Musanto ("Japan Proletarian Party") was a left-wing radical party in Japan which existed from March to December 1937. The party was a political wing of the labor union movement, but it failed to gain popularity due to rising miltarism and inflation. The party was purged in the "Popular Front Incident" that followed the fall of Nanjing from December 1937 to February 1938, but it held 4% of seats in the Diet of Japan by 7 December 1941.
